Suggest an open-source log analyser?

[Alec Taylor]

I use the Python logger class; with the example syntax of:
Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

Can of course easily use e.g.: a JSON syntax here instead.

Are there any open-source log viewers (e.g.: with a web-interface)
that you'd recommend; for drilling down into my logs?

Thanks for your suggestions,

Alec Taylor

I've been experimenting with elasticsearch (to store JSON-format log
messages) and kibana (as a front-end search tool). The jury is still
out on how well it's going to work. It seems like a pretty powerful
combination, but there's definitely a bit of a learning curve to using
it.

I certainly like the idea of logging structured data, as opposed to
plain text. It opens up a world of better ways to search, slice, and
dice your log data.

Because I'm thinking that something with a much less expressive query
interface would serve me better in the long run... e.g.: Redis or
maybe Hadoop

So yeah, if you know of a good one; please share.

Thanks
